Predictive User Modeling with Actionable Attributes

Different machine learning techniques have been proposed and used for modeling individual and group user needs, interests and preferences. In the traditional predictive modeling instances are described by observable variables, called attributes. The goal is to learn a model for predicting the target variable for unseen instances. For example, for marketing purposes a company consider profiling a new user based on her observed web browsing behavior, referral keywords or other relevant information. In many real world applications the values of some attributes are not only observable, but can be actively decided by a decision maker. Furthermore, in some of such applications the decision maker is interested not only to generate accurate predictions, but to maximize the probability of the desired outcome. For example, a direct marketing manager can choose which type of a special offer to send to a client (actionable attribute), hoping that the right choice will result in a positive response with a higher probability. We study how to learn to choose the value of an actionable attribute in order to maximize the probability of a desired outcome in predictive modeling. We emphasize that not all instances are equally sensitive to changes in actions. Accurate choice of an action is critical for those instances, which are on the borderline (e.g. users who do not have a strong opinion one way or the other). We formulate three supervised learning approaches for learning to select the value of an actionable attribute at an instance level. We also introduce a focused training procedure which puts more emphasis on the situations where varying the action is the most likely to take the effect. The proof of concept experimental validation on two real-world case studies in web analytics and e-learning domains highlights the potential of the proposed approaches

Values, attitudes, and goals of future Hungarian food engineers

Over the last few decades Hungarian higher education has been radically transformed, and this transformation was implemented to counter the backwardness that previously plagued the education system. Agricultural education in particular was part of this transformation process, which included the disciplines of food science and related technology. This attempt at transformation yielded only a partial success; student numbers shot up, but there was no subsequent general improvement in the efficiency of higher education. This article is based on two surveys carried out in 1997 and 2007. The students’ values can be characterised as pluralistic and heterogenous. Based on longitudinal research, a shift can be seen toward materialistic and hedonistic values. The motivation for choosing the Faculty of Food Science is varied in nature, mirroring the food industry’s often critical current situation. High schools’ professional orientation is weak. Although the Faculty’s Budapest location is attractive, in the long run this is not sufficient to replace carefully planned promotional work. By structural equation modelling a significant relationship can be proven between the students’ values, their types of knowledge, and their expectations for future types of work.higher education policy, human resource management, food science education, social psychology, empirical research, Agribusiness, Labor and Human Capital,

Using Case Work as a Pretest to Measure Crisis Leadership Preparedness

Today’s leaders must thrive in a world of turbulence and constant change. Unstable conditions frequently generate crises, emphasizing the need for crisis leadership preparedness, which is missing from many business curricula. Thus, the purpose of this work was to develop a learning module in crisis leadership preparedness. As a baseline measure or pretest, 217 graduate students were asked to analyze two crisis leadership cases during the first week of an entry leadership class. Content analysis provided the method to identify where student analyses fell short. These gaps in learning then informed the creation of student learning objectives. Applying inquiry-based learning, I then suggest instructional methods that I incorporated into an active learning module to better prepare today’s leaders for crisis leadership

Australia-Papua New Guinea emerging leaders dialogue: outcomes report

Presents the outcomes of a dialogue involving twenty-two emerging leaders from Papua New Guinea and Australia, from across the business, government, media and non-government sectors. Introduction: The Lowy Institute hosted the inaugural Australia-Papua New Guinea Emerging Leaders Dialogue on 26 November 2013. The Dialogue was convened with the support of the Department of Foreign Affairs and Trade, and was an initiative that arose from the 2012 Papua New Guinea-Australia Ministerial Forum. Twenty-two emerging leaders from Papua New Guinea and Australia, from across the business, government, media and non-government sector, participated in the Dialogue. The Dialogue focused on four main themes: Growing the economy and attracting investment in the Asian Century; Politics and accountability – new expectations; National infrastructure challenges – new approaches; Reform and innovations in the delivery of health and education services. Key findings: Perceptions of Papua New Guinea among the Australian public and business community are narrowly based. They focus on media reports on mining, crime and corruption. These perceptions could be improved by businesses better publicising their successes in Papua New Guinea, the use of creative media and increasing people-to-people links between the two countries through networking and structured collaboration. Social media is rapidly changing the media landscape in Papua New Guinea. Although traditional media continues to be important, the proliferation of mobile phones has given Papua New Guineans, including those living in rural or remote areas, the ability to influence what the media reports and to get their message into the public sphere. Australia and Papua New Guinea, although at difference stages of development, face many of the same challenges in infrastructure and the delivery of services to remote areas. Papua New Guinea could benefit from Australia’s experience in consultative infrastructure planning between governments and business and using emerging, cheap technologies to meet the health and education needs of remote communities

Mobile Broadband Possibilities considering the Arrival of IEEE 802.16m & LTE with an Emphasis on South Asia

This paper intends to look deeper into finding an ideal mobile broadband solution. Special stress has been put in the South Asian region through some comparative analysis. Proving their competency in numerous aspects, WiMAX and LTE already have already made a strong position in telecommunication industry. Both WiMAX and LTE are 4G technologies designed to move data rather than voice having IP networks based on OFDM technology. So, they aren't like typical technological rivals as of GSM and CDMA. But still a gesture of hostility seems to outburst long before the stable commercial launch of LTE. In this paper various aspects of WiMAX and LTE for deployment have been analyzed. Again, we tried to make every possible consideration with respect to south Asia i.e. how mass people of this region may be benefited. As a result, it might be regarded as a good source in case of making major BWA deployment decisions in this region. Besides these, it also opens the path for further research and in depth thinking in this issue.Comment: IEEE Publication format, ISSN 1947 5500, http://sites.google.com/site/ijcsis

Smoothing the Transition to Mandatory Electronic Theses

After a year of voluntary submissions, Caltech is requiring electronic thesis submission for all graduate students effective July 1, 2002. Website development, user education, collaboration between library and campus computing staff, and with faculty and the dean's office are all integral to the transition
